I am building some software on mac os x that uses iobluetooth and corebluetooth to connect/manipulate bluetooth devices.
Like most Bluetooth speakers, the Bluetooth classic network is hidden unless pairing but often the Bluetooth Low Energy network is visible.
I was wondering if there was some way to find a link to the Bluetooth classic section through the Bluetooth Low Energy network and use the details to establish a connection to the Bluetooth classic network.
I am assuming that your speaker is supporting both LE and classic Bluetooth profiles.
So you can connect le first by giving BD_ADDR and all the details for your speaker and later on you can change the transport to classic Bluetooth such as A2DP or SCO.
Thanks.

I have manjaro as my operating system and my wireless keyboard is not working with usb or bluetooth. the bluetooth way, it types after seconds i pressed any button.
I found this page https://linux-hardware.org/?id=usb:0e8f-00a7 but I dont know how to download or anything.
I found out later in life that the keyboard I used was not a legitimate hardware designed from the company (other Bluetooth devices work perfectly), and the USB dongle was exchanged with another hardware.

I am working on a fleet management system that track a fleet fo ambulance using tracking device "Teltonika FMXXXX".
The system should finally operate almost 1400 ambulance, recording their history (Position, speed, ...) and online tracking.
I need to do a stress test on the server. I need to ensure that the 1400 devices will operate probably and the server can handle them.
I need to know how to simulate 1400 devices that send there data packet through TCP protocol?
The only way to do this is to write a basic teltonika GSM-GPS module emulation program that connects to your server and send some fake location etc as many times as you want.
In order to do that you have to read your FM-xxxxx device protocol and see how teltonika's protocol works.
Usually those kind of device protocols are proprietary and you have to ask the ventor (teltonika) to provide you more info about the protocol, in order to implement the whole communication scenario.
you can take a look at this pdf Teltonika FM Protocol

I want to monitor bittorent traffic in my LAN. I used wireshark for that. But I couldn't able to find packets by using wireshark. But can monitor with UDP port number
we can use colasoft packet analyzer. It helps to monitor P2P traffic. Since Skype uses p2p.
Visit http://www.colasoft.com/.
Yeah, I agree. One of Colasoft Capsa 7.8's new features is VOIP analysis.
Below is what I found on their site.
"Capsa 7.8 provides a VoIP analysis module to capture and analyze VoIP calls and graphically display VoIP analysis results, which helps IT staff baseline and troubleshoot VoIP-based networks.
A VoIP view is provided to list all VoIP calls as well as their related statistics and has a lower pane for analyzing voice and video control flows and media flows as well as their jitter, loss, MOS, etc., to visualize analysis data and assess voice and video quality."

I am planning to build a custom hardware /Derivative from designs of Open source hardwares like Beagle bone black.
How to Customize Linux for custom design from open hardwares like Beaglebone?
We start with doing the circuit schematic --> route and do the pcb--> test hardware -->
then where to start the software with for this custom board?
How are new or extra peripherals added to the custom hardware be
mapped to its Linux OS/bootloader?
How does linux for example know i am using a extra usb host or pin
supported peripheral in my custom design in place of few gpio pins on processor as in case of original design?
Thanks

I heard something funny the other day, that I'm not sure that I trust, but at the same time I'm curious if I'm mistaken.
What I heard was that every GSM mobile phone has an RFID chip in them, because the SIM card functions as an RFID chip. Is this true or false?
I don't see how this is programming related, but anyway.
A SIM card does provide "ID" for a wireless ("RF") device, however, it does not provide RFID functionality under the common RFID definition. (A SIM card does not send an ID via RF)
